The present invention relates to illumi- ,usual type and including an alarm spring or nated clocks and more particularly to an alarm driving shaft 17 provided with a windelectrically illuminated alarm clock. ing handle 18. A pinion 19 on the alarm The principal object of my invention is to spring shaft 17 meshes with a pinion on provide a clock which includes a means to alarm striker gear shaft`20 to drive the latter 55 illuminate the dial when the alarm is sounded, and the striker gear 21 fixed thereto. The thus lighting the bed-room and aiding restriker 22 is mounted on a shaft 23 and the sponse to the alarm. latter shaft carries lugs or cams 241 adapted Another object of the invention is to proto be engaged by the teeth of the striker gear vide means on a clock whereby the clock may 21 to vibrate the alarm striker, all in the cus- 60 be illuminated Whenever desired. tomary manner.

A clock dial-13 is carried ying pin 25. The other arm 40 of the bell crank on the front wall 6, and a light bulb 14 is 36 also carries arearwardly projecting lug 41 mounted above the dial, as shown. The clock at its free end and the movement ofthe bell dial includes an alarm-setting dial 15, such crank due to the action of spring 39 is limited p as is common to alarm clocks. by a stop 42 mounted on panel 35 in the path o Within the casing 5 there is mounted a oflug 41. clockwork mechanism 16, preferably of the A switch blade 60 isfpivotally mounted at 43 on the ypanel 35 and is adapted Vto close the light circuit by contacting with fixed contact members 44. An arm 45 is fixed to the axis of blade 60 and extends in a direction substantially diametrically opposite tothe blade and toward bell crank 36. y A spring 46 tends to draw arm 45 upward and thus move switch blade 60 downwardly to'contact with fixed contact 44, but arm 45 is normally held down 0 by the lug 41 on bell crank arm 40, thus keeping the switch in open position.Y TheA stop 42 Vdoes not project sufficiently far forward to be vin the path of arm 45. f

My device may be connected either to bat; teries or to a house lighting circuit, the current being supplied by wires led into the casing 5 through an insulating collar in one side" wall. One side of the circuit is connected to contact blade 60. Light bulb. 14 is ina line 47 0 connecting the other side of the light circuit Y to fixed contact 44.

.Theoperation of my device is as follows 4 lThe alarm may be set in the usual manner, and,l when the alarmshaft 17 is'released to rotate, the actuating pin 25 will move against slidable trip pin 26, depressing the latter and thereby depressing arm 37 of bell crank. This movement will cause arm 40 to release arm on switch blade 60, and the light circuit will thereby be closed.. The ringing of the alarm can be silenced by moving lever on thesside ofthe casing to silent position,

means rotating with said shaft, trip means in the path of driving movement of said actuating means, said tripV means being movable out of the path of reverse movement of said actuating means, and a member nor-V 'said shaft, a reciprocable trip pin in the path! of driving movement of saidactuating pin, said trip lpin being movable out of the path of winding' movement of said gong operating shaft, a switch element, and a mem bernormally holding said switch open and adapted to move to release said switch upon movement of said trip pin.

The bulb 14 will still remain is mounted on a shaft53 extending'through and insulatedfrom the front wall 6 of the cas- 0 ing, .andswitch blade 60 is mounted on this shaft, .as shown at l43. It therefore results that movement of knob 52 to off position lighted and will illuminate the clock dial and moves arm 45:0f the switch blade back under the'bell crank arm 40, openingv the light circuit.l c, Y v f Thebulb maybe lighted kwhen theiknob l52 isfinfoff position by means of awswitch 54, preferably of the rotating vsnap type, mounted inone yside wall of the casing 5. This switch is on a line 55 paralleling line 47, and bulb 14 may thus yhe illuminated regardless, of whethery Aswitch, blade` is in open position. v l l It will: be understoodl from the above lthat the operation of switch blade GOis very rapid.
